A Regional Seats system of election was outlined in a spring 2001 article in this publication. Some recent general elections show the usefulness of the system. In particular, an RS system would provide more diverse party representation in certain areas now dominated by one party or another. One need only consider metropolitan Toronto-Mississauga to see the truth of this.
In the recent Ontario provincial general election, the Progressive Conservatives won no seats in metro Toronto-Mississauga, which was a repeat of their performance in 2007. Of the 28 seats available, the Liberals took 23 in 2011 and 24 in 2007. The same electoral districts are used federally, and the Liberals took 25 or more of the seats in the elections of 2004, 2006 and 2008. Only in the most recent federal election was the outcome any different.
